Definitely doable with tons of different ways to accomplish it. Basically, you can use a widget that allows for the execution of PHP or modify your theme files to execute PHP in the sidebar. The main function you will need is get_post_meta. You also need to access the post/page/CPT ID. You can use code like the following to get your post meta displayed.

Obviously, you need to change the "my_post_meta_key" value to a key that corresponds to the meta data that you want. Also, there are other ways to access the current page/post/CPT ID, but since I do not know your specific context, this will work for most situations.

How does this answer differ from the other answers? Or in which way is it more verbose than the others?
